Advice on ‘74 Duster

well, as far as the timing chain goes, the car was lacking power and yeah it did well on my 300 plus mile trip home but I think the trip was just too much and brought all these issues to the surface. From a dead stop the car wont even break the rear wheels free at all.
I thought maybe just a good tune up would help my loss of power but the timing was off and I couldn't get it right. I was guessing the chain was stretched, and I was right. Along with the distributor being corroded inside also didnt help. This car must have sat for awhile is my guess.

The gas tank appears to be leaking at the rear of the tank right in the middle rear of the tank.

I think the carb just needs rebuilt but I dont know how to do that and just going to replace it

Thanks everyone for the help and understanding. Ive been in other groups before and some just like to revel in your misery.
I am excited to get the car running like it should be, and I cant wait for that day but until then I am continuing to save more money to make the repairs as I am keeping this old mopar.

The motor mounts, I honestly didnt even look at them closely.
as far as getting money back from the seller, I dont think that will happen. Honestly I dont think he realized the issues the car had, he was a chevy guy and got this car in a package deal with a 69 camaro ss. He didnt know much about it.
I should have known better to buy a mopar from a Chevy guy:mad:
Once the issues are resolved these cars are pretty prblem free. That is the beauty of old mopars they can keep on going with minimal issues. I drove my dart sport 1st with a slant 6 never an issue. Heck I even neglected to adjust lash and when I finally did it was still in spec! Then came the 360 ran super until some issues with faulty coil and distributor pick up all @ once. But these things will happen with all types cars regardless of make. Just part of owning a classic. :)
